Neela is buying shirts that are on sale at two for the price of one. The original price of each shirt was s dollars. She buys 4 shirts for $24.

Which equation shows an equality between two different ways of writing how much Neela spends on the shirts?

Answer:

409[tex]cm^{2}[/tex]

Step-by-step explanation:

The area of the box wuld be c times d which is 15 times 17 which is 255.

the area of the triangle is [tex]\frac{1}{2}\\[/tex] (base x height) = [tex]\frac{1}{2}\\[/tex](28 x 11) = 14 x 11 = 154

154 + 255 = 409. area of 2D shape's unit is squared, so 409 [tex]cm^{2}[/tex]

Answer:

a= 40, b= 50, c= 115

Step-by-step explanation:

a-

There is a theorem for a that gives you the answer:

Vertical angles are congruent

If the vertical angle of a is 40°, then a is also 40°.

That is what the theorem says.

b-

This one is kind of difficult, but let me break down the steps.

Now you already know that a is 40°, and the other angle besides b is a right angle because it shows a square, or 90°.

And now you need to know another law:

Every single triangle's angle adds up to 180°.

Now, this is basically a subtraction problem.

If two of the angles are there, and you know that all of the angles of a triangle add up to 180°, then you just need to know what 90 + 40 + x = 180 is

90 + 40 = 130

130 + x = 180

Subtract 130 from both sides

130 + x = 180

-130        -130

x=50, which means that all of the angles add up to 180°, or following the law.

c-

This one is different as well.

You can very clearly see that it is a straight line that crosses 65° and c.

There is one more law as well:

A straight line is 180°.

If that line that 65 degrees and c sits on is straight, that means that-

65 + x = 180, or

180 - 65 = x

180-65 = 115, and c=115.

It also follows that law; 115 + 65 = 180, which means that it is correct.

Hope this helps :)

Answer:

a=2.8

Step-by-step explanation:

Answer:

(3/4 * 12a) + (3/4 * 8) = 31.2

                               a = 2.8

Step-by-step explanation:

[tex](\frac{3}{4}*-)+(-*8)=-[/tex]

[tex]\frac{3}{4} (12a + 8) = 31.2\\\\\frac{3}{4} (12a)+\frac{3}{4} (8)=31.2\\\\9a+6=31.2\\\\\ \ \ -6 \ \ \ \ \ \ \ \ -6\\\\9a = 25.2\\\\/9 \ \ \ \ \ /9\\\\a=2.8[/tex]

Answer:

(3/4 * 12a) + (3/4 * 8) = 31.2

                               a = 2.8

Answer:

The mean number of cups of coffer per person was 3.2 cups.

There is nothing in the problem that leads me to believe that the surveys were biased (Was there more to this problem?).

Therefore, we will use all of the values to find the mean. Add up all the values and we have a total sum of 48. Now, divide by 15 to get a mean on 3.2.

Answer:

The conclusion is not correct

Step-by-step explanation:

At first it might seem as though the conclusion is correct, seeing as the table has the correct input and is done correctly, but it is the wording of the second sentence next to the table. The question says "you ask 100 randomly chosen high school students..." , Yet the second sentence says "You conclude that 15% of Residents in your town..." Therefore, they aren't relevant to the graph which means the conclusion is wrong

Answer:

Grocery store is the correct one ...

brainleaist please

Answer:

Yes it is grocery store.

Step-by-step explanation:

Hii :)

We know that there are 2 boys, so we should divide 2 by 43. But first..

We need to add the total amount the boys spent together, then subtract,then divide

13+5=18.

The boys spent a total amount of 18 cents.

Next, we need to subtract 18 by 43.

43-18=25.

So, if we were to spilt the 25 evenly, or divide by 2, the answer would be 12.5 cents. But, we need to find what they had to start with.

43 divided by 2 is 21.5. So each boy had 21.5 cents to start with.

Answer:

73

Step-by-step explanation:

180-107=73

Answer:

B

Step-by-step explanation:

Answer:

first, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year.

Solving our equation:

A = 6000(1 + (0.03 × 4)) = 6720

A = $6,720.00

The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 3% per year for 4 years is $6,720.00.

Answer:

$380

Step-by-step explanation:

If he got 4% interest over the three years then he gained $380 because 9,500 divided by 100 is 95 multiplied by 4 is 380 and thats how much he gained. Total he would now have $9,880.

Answer:

y = x + 5

Step-by-step explanation:

Slope (m) formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-4}{3-(-1)}\\\\m=\frac{8-4}{3+1}\\\\m=\frac{4}{4}\\\\m=1[/tex]

y = mx + b

y = 1x + b  OR y = x + b

(-1, 4)

y = x + b

4 = -1 + b

+1   +1

5 = b

y = x + 5

Check your answer using y = x + 5 and (3, 8):

y = x + 5

8 = 3 + 5

8 = 8

This statement is true

Therefore, our final answer is, y = x + 5.
